Thanks for the idea
I attempted to run the SQL 2008 SP 1 installer from start/run with no other windows or applications open - failed again.
Then I checked the Windows 2008 features and installed the following:
Windows Process Activation Services
- .NET Environment
Prior to this (in order to do the initial SQL 2008 install) I had to install the .NET Framework 3.5.1 Features - .NET Framework 3.5.1
Reran the SP1 installer - ran successfully.
